UFS campuses are transforming into research instruments while simultaneously improving campus operations through the Smart Grid initiative.

Imagine living in a smart home. Imagine monitoring your household’s electricity usage via an integrated system that would notify you of your daily electricity use, peak usage times, and tariffs and consumption at the location of the house. As a user, you would be able to take advantage of such information in order to manage your resources in a more efficient manner. This is just one example of what a Smart Grid can do.

The University of the Free State’s (UFS) Faculty of Natural and Agricultural Sciences has teamed up with the Department of University Estates to drive our very own Smart Grid initiative that is transforming the university’s power network into one with full control and monitoring. “A Smart Grid allows for resource optimisation and asset protection, especially in times like these,” said Nicolaas Esterhuysen, Director of Engineering Services. 

Why is it important for our university to have a Smart Grid?
Dr Jacques Maritz, Lecturer of Engineering Sciences at the Faculty, considers a Smart Grid the natural evolution of power grids in the era of Big Data, IoT and Machine Learning. Resources such as electricity, water and steam can now be monitored and controlled to promote savings and the protection of valuable infrastructure. “Aiming towards Smart Grid status, the UFS will improve resource service-delivery to its staff and students, while sculpting a digital twin of its campus’s power grid, consumer network and resource generators,” he added.
  
How will a Smart Grid improve student success?
The integrity, sustainability and continuous supply of energy directly affects the academic project on all three campuses. The implementation of a Smart Grid could allow improved service delivery and reaction time when any utility is interrupted, as well as maintaining the valuable infrastructure that serves the UFS community.

In what way does a Smart Grid improve the lives of staff members?
According to Dr Maritz  and Esterhuysen: “A Smart Grid will support staff to perform their teaching and research duties in a seamless manner, continuously optimising the energy that they consume to enable full comfort and reliability in energy supply, whilst simultaneously generating savings in energy and preventing wastage.”

The UFS already boasts most of the fundamental building blocks associated with the Smart Grid initiative, especially focusing on monitoring, grid protection, centralised and decentralised solar PV generation and software platforms to serve all these domains. However, to integrate all of these domains into one digital real-time paradigm will be a first for the UFS.

Some examples of the UFS smart grid applications currently in practice
Real-time remote monitoring and control that focuses on the following:
- We are able to detect power outages and don’t have to rely on customer complaints. This enables faster response time and fault identification, thus less downtime and an increase in reliability;
- Solar plant generation; 
- Monitoring our standby generation fleet; 
Identifying usage patterns and saving thereof;
Benchmarking buildings in terms of application usage, area or occupancy to determine energy efficiency and identify savings; and condition-based preventive maintenance that will increase reliability while saving costs.

Three receive PhD degrees in Architecture at Winter Graduation ceremony

Three graduates from the University of the Free State’s (UFS) Department of Architecture received their PhD degrees at the 2015 Winter Graduation ceremony on the Bloemfontein Campus. According to Prof Walter Peters from Architecture, this is the first time in the history of the UFS that three PhD degrees in Architecture have been awarded simultaneously. It is country-wide a rare occurrence for three PhDs to be awarded in Architecture at one graduation ceremony.

“Previously, the UFS has only ever awarded a single PhD in Architecture, and that was in 1987, to Leon Roodt, a former head of the department. The first UFS honorary doctorate in Architecture was conferred on Gerard Moerdijk, architect of the Afrikaner church and the Voortrekker Monument. Gawie Fagan and Prof Bannie Britz, late head of the Department of Architecture, were other recipients of an honorary doctorate in Architecture,” said Prof Peters.

At the 2015 Winter Graduation ceremony, the UFS conferred PhDs in Architecture on Hendrik Auret from Roodt Architects in Bloemfontein as well as on Gerhard Bosman, and Madelein Stoffberg from the UFS Department of Architecture.

Dr Hendrik Auret

As an Architecture student at the university, Dr Auret obtained the degree BArchStud in 2004, a BArchStud (Hons) in 2005, and a March (Prof) in 2006, all cum laude. His Master’s design dissertation was judged the best from all South African Architecture learning sites, earning him the coveted ‘Corobrik Architectural Student of the Year’ award.

The work of the Norwegian architect and theorist, Christian Norberg-Schulz, served as the basis of Dr Auret’s PhD thesis, Care, place and architecture: a critical reading of Christian Norberg-Schulz’s architectural interpretation of Martin Heidegger’s philosophy, which considered the cogency of Norberg-Schulz’s architectural ‘translation’ of the German philosopher Heidegger’s thinking.

Dr Gerhard Bosman

On obtaining his BArchStud. and BArch degrees at the university in 1993 and 1995 respectively, Dr Bosman immediately joined the part-time staff of the Department of Architecture. As a lecturer in Building Construction, he developed an interest in vernacular and indigenous methods and techniques. Consequently, he built the first family home in Bloemfontein, for his wife, Debbie, and their two children, of earth construction, which been previously but erroneously considered inferior.

Despite that negative perception, Dr Bosman persuade the university to allow him to undertake post-graduate studies at the International Center for Earth Architecture (CRATerre-ENSAG) within the Ecole d' Architecture de Grenoble, France, from which institution,he was awarded the DPEA-Architecture de Terre qualification in 2000. In 2001,Dr Bosman was appointed to the full-time staff.

In 2003, when the opportunity arose, he became involved with SANPAD, the South Africa-Netherlands Research Project on Alternatives in Development, which lead ultimately to his PhD thesis: The acceptability of earth-constructed houses in central areas of South Africa.

Dr Madelein Stoffberg

In 2005, Dr Stoffberg enrolled as an Architecture student at the UFS, obtaining her BArchStud degree in 2007, the BArchStud (Hons) in 2008 and the March (Prof) in 2009, the latter cum laude. Immediately on graduating, Dr Stoffberg was appointed to her position as a part-time junior lecturer in the Department of Architecture.

During her studies, her attention was drawn to the concept of the spatial triad of Henri Lefebvre. Fascinated with the conceptand by the development of community centres as a contemporary architectural typology, she began her PhD degree.  

Entitled Lived reality, perception and architecture: two community centres interrogated through the lens of Lefebvre’s spatial triad, Dr Stoffberg investigated the relationship between the spatial understanding of the project architect and the community of two completed buildings in Port Elizabeth. She established a mismatch in perception, representation, and use of space, which could be bridged, however, by way of a qualitative research approach, instead of a quantitative one.
